UCC28950PWR TI DC DC Switching Controllers
The UCC28950 is a phase-shifted full-bridge PWM controller with synchronous rectification control, operating from an 8-V to 16-V supply. It features programmable switching frequency up to 1 MHz, adaptive zero-voltage switching (ZVS) for high efficiency, and dual 100-mA outputs for driving power MOSFETs. The device includes cycle-by-cycle current limiting, overvoltage protection, and thermal shutdown. Packaged in a 24-pin TSSOP (PW), it is ideal for high-efficiency telecom and server power supplies, DC-DC converters, and industrial power systems requiring high-density power conversion.
